However‚ the weight of a given piece of evidence is ultimately

(Lynch & Duval‚ 2011). This theory better known as "Locard’s Exchange Principle” is the foundation of the forensic study of trace evidence as we know it today. Trace evidence is very important in forensic investigations as this evidence includes different types of microscopic materials as well as some materials that are easily visible to the naked eye. Trace evidence examination is the analysis of small particles in order to assist in establishing a link between a suspect and the victim of a crime

Fiber Optic Connector Assembly The three fiber geometry parameters that have the greatest impact on splicing performance include the following: Cladding diameter—the outside diameter of the cladding glass region. core/clad concentricity (or core-to-cladding offset)—how well the core is centered in the cladding glass region fiber curl—the amount of curvature over a fixed length of fiber These parameters are determined and controlled during the fiber-manufacturing process. As fiber is cut and

spreading of a light pulse as it travels down a fiber when light pulses launched close together(high data rates) spread too much and result in errors and a loss of information. The spectral width determines the number of different wavelengths that are emitted from LED or laser. One way to reduce chromatic dispersion is to narrow the spectral width of the transmitter. Chromatic dispersion can be compensated for with the use of dispersion-shifted fiber (DSF). Laser has a more narrow spectral width

Saturated fats are mostly in meats‚ dairy products and tropical oils. Saturated fat raises both bad cholesterol and good cholesterol‚ while trans-fat only raises bad cholesterol. This makes trans fats technically worse than saturated fats. The better fats would be monounsaturated and polyunsaturated. Monounsaturated will lower your cholesterol

Fiber Optic Safety Rules 1) Keep all food and beverages out of the work area. If fiber particles are ingested they can cause internal hemorrhaging 2) Do not smoke while working with fiber optic systems. 3) Always wear safety glasses with side shields. Treat fiber optic splinters the same as you would glass splinters. 4) Never look directly into the end of fiber cables until you are positive that there is no light source at the other end. Use a fiber optic power meter to make certain the
